VAPORIZER FOR EXPLOSIVE-ENGINES.

Patented July 30, 1907.

Application filed anuary 19. 1907. Serial ND- 353,008.

To all whom it may concern:

Be it known that I, CHARLES I. LONGENECKER, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Vaporizer for Explosive-Engines, of which the following is a specification:

My invention relates to improvements in Vaporizers for explosive engines in which gasolene or alcohol may be used to supply the explosive fluid, and the objects of my improvement are: First, to provide a mechanism that will operate in a manner to finely divide the liquid and thoroughly mix it with a proportionate amount of air preparatory to its admission to the valve chamber of the engine; and second, to provide a mechanism that is simple and reliable, and one that can be readily adj usted to operate with either gasolene or alcohol as the motive fluid.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which- Figure 1 is a vertical section of the entire mechanism. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is a cross section of the feed cup on line A 13 of Fig. 1; and Fig. 4 is an enlarged detail representing a part of the feed and vaporizing mechanism.

Similar reference numerals designate like parts throughout the several views.

1 represents a portion of a valve chamber of an engine to which my invention may be applied, 2 is a conduit having a substantially uniform area throughout its length and having its lower end communicating with the valve chamber and its upper bell-shaped end provided with a cover 3 and lateral openings 4 beneath the cover for the free admission of air to the interior of the 'conduit. Intermediate the upper and lower ends of the conduit there is provided an internal annular rib 5 that operates to contract the area of the conduit at that point for the purpose of accelerating the current of air in its passage through the restricted channel, and 6 reprr-st-uts a removable ring adapted to rest up n th ri and provided with a central opening having a less :m-u

l is a cylindrical bridge 13 joining the walls of the cup than that l'ornu-tl by the rib, tor-.1 purposo in luovscribed later.

7 represents a feed-cup preferably formed integral with the conduit 2 and offset therefrom. The feed cup is provided at its lower end with a feed pipe 8 communicating with a source of fluid supply (not shown), and an overflow pipe 9; and 10 represents a loose cover closing the otherwise open opposite end of the cup. The lower half of the cup is divided into three compartments by means of partition walls 11 and 12 connecting the outer wall thereof with the inclosing wall of the conduit, and the feed pipe communicates with one of the outer compartments and the overflow pipe with the other. Approximately in the same plane as the upper sides of the partitions, and parallel therewith,

intermediate the partitions and spanning the middle compartment. The bridge is provided with an axial bore communicating with the interior of the conduit and threaded at its outer end to receive the stem of a '60 needle valve 14, and at its inner end the stem 15 of a fer-cl nozzle having an axial bore in line with the bore of the bridge piece. the stem having at one end a seat for the valve and at its opposite end a vcrt ically extending head 16, projecting upwardly in the conduit to a plane adjacent that of the contracted portion thereof. The head is provided with a vertical annular channel 17 extending downward and communicating with the axial bore of the stem, and a cap 18 is secured to the head by means of a screw 19 and projects beyond the outer walls of the channel in a manner to cover the same. Between the cap and the central portion of the head is secured a thin washer 20, preferably made of paper, and having a thickness sufficient to provide only a very minute intervening feed opening between the cap and the end of the outer wall of the channel for the outflow of the motive fluid to the air conduit. Surrounding the valve stem at the inner end of the axial bore of the bridge is a chamber 2], and communicating with the chamber and the lower part of the middle compartment of the feed cup is a vertical feed duct 22. A constant supply of fluid is maintained in the feed cup sufficient to keep the level thereof above the partition walls and in a plane slightly below the feed opening communicating with the air conduit.

In operation the suction action of the engine produces a partial vacuum in the conduit 2, which causes the fluid to rise in the annular channel of the feed nozzle and flow through the narrow feed opening below the cap, where it is met by the inflowing current of air and is finely diffused and mixed therewith in its passage to the valve chamber.

ln the use of alcohol as a motive fluid, it has been lonn l hat it roonirt-s nnn'ti n-[- to pro wrlv mix itwith nil than wln-n gusolcnzis us -(1 and lo provirhl] u tlo |t v ol viIln-r llnhl. l lnlw' rlt-visml :i Int-ans tor r gulilting the force of the air cnrrt-nt as it meets the [low of motive fluid, consisting in means for adjusting the area of the air conduit immediately in advance of the feed inlet.

When gasolene is used for the motive fluid, the area of the contracted portion of the air conduit. is of maximum dimensions as governed by the size. of the annular rib 5. and the air consequently flows with minimum speed i hen meeting the inflow of motive fluid.

When alcohol is used the area is reduced by means of the ring 6, having an opening of minimum dimensions being placed in the conduit and supported by the rib 5, and thereby causing the air to flow with a maximum velocity as it meets the motive fluid.

What I claim as my invention, and desire to secure by Letters Patent. is:

1. A vaporizer [or explosive engines comprising, in combination, an air conduit communicating with the engine 5 cylinder, and having, a substantially uniform area throughout its length a feed cup in which the motive lluid is maintained at a constant level. a feed outlet from said cup to said air conduit, said outlet having a feed nozzle within said air conduit and having its delivery end above the level of fluid in said cup. said air conduit having its area contracted adjacent the delivery end of said feed nozzle by means of an internal annular rib projecting inward from the wall of said conduit.

2. A vaporizer for explosive engines comprising, in com bination, an air conduit communicating with the engine cylinder. and having a substantially uniform area throughout its length a feed cup in which the motive fluid is maintained at a constant level, a feed outlet from said cup to said air conduit, said feed outlet having a feed nozzle within said air conduit and having its delivery end above the level of fluid in said cup. said air conduit having its area contracted adjacent the delivery end of said feed nozzle by means of a removable ring having a central opening of uniform area throughout its length of less area than that of said conduit.
